Title: A self-hardening resinous composition
IPC: H01B3/40
Filed: 1964-10-28
Abstract: 1,073,382. Electric insulation. MINNESOTA MINING & MANUFACTURING CO. Oct. 28, 1964 [Nov. 14, 1963], No. 44052/64. Heading H1A. To reduce the exothermic heat produced when a liquid resin hardens in the formation of an insulation member, the liquid resin is first loaded with capsules comprising a droplet of dielectric oil contained in a resinous shell. The capsules of 5 to 60 microns in diameter are produced by dispersing transformer oil in very small droplets in an aminoplast resin composition by vigorous agitation and then allowing a resin coating to form on them; the proportions and constituents of this mixture are given in the Specification. After adding the dried capsules to a liquid epoxy resin reaction product of epichlorohydrin and glycidyl ether of bisphenol A and its curing agent triethylenetetramine the mixture is forced into a mould such as the cable termination shown in Fig. 1 and allowed to harden. The specific gravity of the capsules is made substantially the same as the liquid resin. The use of the capsules reduces the temperature rise occurring when the resin hardens and so avoids cracking and the production of voids in the insulation. The liquid resin and hardening agent are conveniently contained in a plastics container but separated by a membrane which is ruptured to allow the two to mix prior to the filling of the mould, the capsules being included in either or both compartments. The liquid epoxy resin may in part be replaced by epoxidized 1,4-butanediol, and other suitable amine curing agents are aminoethyl piperazine, amine-terminated polyamide resin and tridimethylamino - methyl - phenol. Other dielectric liquids may be used such as chlorinated biphenyls.

Title: Electric system for playing a musical instrument
IPC: G10H3/08
Filed: 1964-11-02
Abstract: 1,123,614. Electrical control of musical instruments. T. M. PAMPLIN and R. M. BULLEY. 13 Dec., 1965 [2 Nov., 1964], No. 44566/64. Heading G5J. A musical instrument is caused to play by signals characterizing the keys played on a separate keyboard, which may be attached to an instrument or be a dummy, and the signals may be stored, for example on a magnetic tape, between their production and use. Signalreleasing means are associated with each key and may be contact switches or be modulators controlled according to the velocity of the key. The signals may identify both the keys played and their expression. Each may be, for example, a modulated pulse or series of pulses of a sinusoidal carrier with a frequency or combination of frequencies which identifies the key. They are passed through a single communication channel, of any convenient length, optionally are stored on magnetic tape, and when play is desired are selected by band-pass filters, demodulated and amplified and passed to electromagnetic actuators which operate the controls of the instrument. Conveniently the signals recorded on tape have band widths of over 100 c/s and one octave of tape recording band width accommodates signals identifying the keys of one octave of a piano. The electromagnetic actuators may be moving coil devices.

Filed: 1973-09-25
Abstract: 1412828 Automatic phase control SIEMENS AG 25 Sept 1973 [26 Sept 1972] 44852/73 Heading H3A An arrangement in which a local carrier oscillator in a receiver is synchronized with a transmitted carrier comprises: a test signal generator at the transmitter which modulates the carrier during a period when no other signals are being transmitted with a signal having two consecutive equal amplitude values; a detection circuit in the receiver which produces a control signal if the amplitude values of the demodulated test signal are unequal; and means, also in the receiver, for adjusting the phase of the local carrier in dependence on the control signal. The test signal comprises two pulses of equal and opposite amplitude A1, A2, Fig. 2. In one form of detection circuit, Fig. 3, the demodulated test signal B is applied via diodes 34, 35 and inverter 27 to two capacitors 36, 37 which store the peak values of the two pulses B1, B2 respectively. The two capacitors are connected to the inputs of a differential amplifier 30 whose output is connected to a threshold circuit 46. The phase adjustment may be made in two stages by deriving, from the outputs 47, 48 and the input B, three digital signal MNP, Figs. 5, 6 (not shown), which adjust the phase shift stepwise into the correct quadrant, after which a fine adjustment may be made. The fine adjustment may be made by the output from a digital counter (64), Fig. 4 (not shown), which is controlled by the output 47 of the detector of Fig. 3. The test signal may be generated automatically whenever the measured phase error becomes too large, or may be initiated manually.

Title: Improvements in and relating to the determination of vacuum existing within containers
IPC: G01M3/38
Filed: 1961-12-18
Abstract: 1,014,763. Photo-electric inspection devices. OWENS-ILLINOIS Inc. Dec. 18,1961 [Dec. 29, 1960], No. 45196/61. Heading G1A. In apparatus for testing a continuously moving line of individual containers to ensure that their vacuum-seal is satisfactory the container caps are each provided with a flexible panel which is concave when the seal is correct and the panels are viewed by a photo-electric device to check their shape. The containers C carrying the caps D may be fed through the testing apparatus by means of a conveyer 42. The apparatus consists of a main sealed housing 40 adjustably mounted on vertical column. In the housing a light source in a suitable mounting 65 provides a beam of light which is directed by a lens to reflecting prism 66 and brought to a focus in the plane of motor driven disc 67 which is provided with a plurality of spaced apertures to cyclically interrupt the beam. The interrupted beam is collimated by lens 68 and directed through a window in the bottom 47 of the housing on to the caps D as they pass. Light reflected from the caps passes back into the housing and falls on a light gathering lens 71 which carries an axial opaque mask. Light passing outside the mask passes through a further aperture and on to a photo-sensitive device 73. The source, lens, prism, chopper disc and collimating lens are mounted as a sub-assembly on angularly adjustable plate 70 and the detector unit is likewise mounted on plate 74. Angular adjustment of plates 70 and 74 about a pivot substantially in the plane of the caps D is made to ensure that light from the source is reflected from the caps along the axis of the detector system. If the flexible panels are correctly concave the reflected light is focussed on to the mask on lens 71 and absorbed. To ensure as little light as possible reaches detector 73 the central portion of the aperture in front of it is also masked and the optical system dimensioned so that reflected light from the housing window is brought to a focus on this second mask. When a faulty container passes its panel is not concave and reflected light from it passes round the outside of the mask on lens 71 and is directed to detector 73. To ensure effective testing only takes place when the containers are correctly positioned under the apparatus, housing 40 carries small depending units on either side of the container path one of which houses a light source and lens and the other a lens and photo-transistor. As each container passes it obstructs the light from the source falling on the photo transistor whose output controls a trigger circuit to produce a gating pulse immediately following the passage of a container C. This gating pulse is fed to an "and" gate with the output of detector 73. Signals appearing at the gate output are shaped and used to control a pneumatic ejection device 160 positioned to remove containers with defective seals from the conveyer.
